I am trying to test out a few simple Cairo programs, but I am having trouble figuring how to include the source files. I have installed the Cairo library - it's just a question of how to let gcc know...
I have the .h files (including cairo.h) installed in /usr/local/include/cairo
I have the .dylib files installed in /usr/local/lib and /usr/local/lib/cairo
Are there any other components of the installation I should be aware of? (I just did 'make install' to install the library)
I am trying to compile like this:
$ gcc cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/
My cairoTest.c file starts out with:
include <cairo.h>
gcc is finding cairo.h, but it gives the following error message. I think it is not linking to the .dylib files correctly, but I'm not sure. I'm still new to compiling/linking.
gcc cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/cairo

What should I be doing differently to include the Cairo library in my compilation?
Thanks,
Try to compile with
gcc -Wall -g cairoTest.c -I/usr/local/include/cairo -L/usr/local/lib/ -lcairo -o cairoTest
(but you probably need other libraries, perhaps thru $(pkg-config --cflags --libs cairo) or similar)
And your file should start with
#include <cairo.h>

I went to http://www.linuxfromscratch.org/blfs/view/svn/server/apache.html
From there I found two dependencies Apr-Util-1.5.4 and PCRE-8.40.
I configure the build of apr-util with:
./configure --prefix=/usr/local/mac-dev-env/apr-util-1.5.4 --with-apr=/usr/local/mac-dev-env/apr-1.5.2 --with-openssl=/usr/local/mac-dev-env/openssl-1.0.2k --with-crypto
Most important was to build apr-util with --with-openssl=/usr/local/mac-dev-env/openssl-1.0.2k --with-crypto.
I then built pcre-8.40 as I had been attempting to build with pcre-8.39.
I believe the root cause was not building with apr-util-1.5.4 with the --with-openssl=/usr/local/mac-dev-env/openssl-1.0.2k --with-crypto options.
My configuration before make for apache-2.4.25 was:
./configure --prefix=/usr/local/mac-dev-env/apache-2.4.25 --enable-so --enable-ssl --with-ssl=/usr/local/mac-dev-env/openssl-1.0.2k --with-apr=/usr/local/apr --with-apr-util=/usr/local/mac-dev-env/apr-util-1.5.4 --with-ldap

Could someone tell me where the problem is?

Since you're using AGL, looking at the reference for AGL, you need to import the framework AGL along with OpenGL.

I know the gmp library is installed correctly as I have another xcode project linking to it that is compiling correctly. Any ideas as to why this is happening?
Forgot to say I have added paths to the header file and library for GMP as well as add the -lgmp flag under Other Linker Flags
SOLVED: see this answer.
I think xcode runs in a Debug configuration first, where no optimization is performed and no inlining is carried out. This means any inline function must also be made static.
I'm trying to compile a C/C++ program that uses SDL on a OS X 10.6.8 but I'm having some errors on the linking stage, the code compiles but fails to like due to some missing symbols. The error is:

I checked with the file command and the libraries are either x86_64 only or universal with both i386 and x86_64 versions.
Is there a way for me to determine what exactly is causing this error? A way to check the libs that are being included or any way to help debug the problem?
I don't know if it helps but this is what my Makefile creates, I removed file names to make it short, and the KNT flag is just something I'm using for preprocessor conditions:
/opt/local/bin/g++-mp-4.5 -DKNT=1 -Wp,-M,-MP,-MT,-MF, -std=c++0x -Wall -I source -O1 -funroll-loops -c -o
Thanks.
